To all whom it may concern .1

Be it known that I, WALTER S. AnAMs, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Car-Seats, of which the following is a specification.

The object of this invention is to make a car seat structure in such a manner that the shifting seat section and the movable back section are so connected together that both can be bodily removed from the supports when the back is turned to a central position, but when the back is moved either to one side or to the other then the seat section and the back are locked to the supports so that they cannot be accidentally displaced.

The invention also relates to certain details which will be fully described hereinafter, reference being had to theaccompanying drawings, in which:

Figure l is an end view of the car seat showing the back in one of its two normal positions at one side of the seat section; Fig. 2 is a side view; Fig. 3 is a detached perspective view, showing the seat and the back section lifted off of the supports; Fig. 4 is a perspective view of the seat supports; Fig. 5 is an end view of the car seat, showing the back in the mid position so that the seat and theback can beremov-ed from the seat supports; Fig. 6 is a detached view of the walglbracket; Fig. 7 is a viewof the upperportion of the pedestal support; 8 is a detached perspective View of the end of the seat cushion; Fig. 9- is a view of the bracket of-the back section, Fig. 10 is a detached viewof one of the arms;'and Figs. 11 and 12 are diagrams illustrating the pins in different positions. I *Heretofor-e, the back section Was hinged to the frame of the seat structure and the seat section was removable from the mechanism and from the back so that it couldbe lifted off oiithe supports in order that access could behad to. thespace under the seat, but the back section and the mechanism remained. Thisdid not give an entire clear space for cleaning or repairs. In the event of arepairto theoperating mechanism, the carwould-have to be transferred to the shop and, consequently, was out of commission until therepair was made. In the construction shown,'i:n-the event of repairs being required,the seat section and the back section can be removed and a duplicate section placed in position so that the car is always in commission. This is an important feature.

By coupling the seat proper, or cushion, and the backtogether there is no liability of the mechanism becoming disarranged.

In the present instance, 1 is the side of a car on which is secured a bracket 2 having curved seat supports 3.

4 is an aisle pedestal having a curved seat support 5, curved similarly to the seat support 3., and projecting from each seat support is an extension 6 having a T-slot 15 therein for the reception of the pivots at tached to the seat section 7. This seat section has curved ribs or rockers 8 resting on the curved seat supports so that when the seat section is moved to either side it will slide on these curved seat supports and will assume a slight angle, as in Fig. 1, with the front of the seat raised a greater distance from the floor than the back thereof.

9. is the back section made in the usual form and havingbrackets 16 secured at each edge. Each of these brackets has a central pivot pin 13 and on each side of this central pivot pin are two pivot pins 17.

10, 10 are two parallel links pivoted to the pins 17 17 respectively and to the pins 18, 18 respectively on the seat section so that the back, as it is shifted from one side to the other, will assume a proper angle with respect to the seat section. A shaft 12 extends under the seat section and has its bearings in the rockers 8 and end plate 8 and is located between the pivot pins 18.

11, 11 are two fiat arms, one located on each side of the seat structure. One end of each arm is secured to the shaft 12 and the other end is mounted on the pivot pin 13 on the bracket 16 of the back section. This plate maybe held in position by one or two screws at the pivot points 13 or 12, as desired. Other means" of fastening may be employed, if desired. In the present instance the plates 11 are broad and flat so as to overlap the two parallel links 10 and these links may be shaped in any manner desired to make the connection more or less ornamental. The flat arms 11 retain the links in position on their pivot pins without other fastenings, as shown in the drawings.

The ends of the shaft 12 project beyond the arms 11 and extend into the T-slot l5 11, at the wall end of the seat, is a pin 14:,

which is located a given distance from the shaft 12 and near the aisle end is an arm l1 which is secured to the shaft 12 and extending under the seat section. This arm 11 has a pin 14 in line with the pin 14. These two pins 14 and 14: are located in the narrow vertical portions 20 of the T-slots 15 in the bracket and pedestal, while the projecting portions of the shaft 12 are located in the transverse portions 21 of the T-slots 15. When the back is in either of its two normal positions, as in Fig. 1, then the ends of the shaft 12 are under the overhanging portion 19, Fig. 11, so that it will be impossible to lift the seat sections off of their supports. Furthermore, the outer edge of the seat section is locked to the support, which prevents it from being lifted when a person occupying the seat rises suddenly therefrom. In light seat structures, such as those used in trolley cars, this is annoying, yet it often occurs if the seat is not firmly secured to its supports.

-When the back is moved to the central position, as shown in Fig. 5, then the shaft 12 Will be in line with the pins 14: and l4: and also in line with the portion 20 of the T-slot, as in Fig. 12, so that the entire structure can be raised clear of the supports and removed. The moment, however, the back is moved either to the right or to the left, the pins lei, 14, act as pivots and the ends of the shaft 12 pass into the transverse slot 21 out of line with the vertical slot 20, looking the seat structure to its supports.

While I have shown a bracket at the wall end of the car, a pedestal may be used at this end, as well as at the aisle end, and while the invention is particularly adapted for a car seat, it can be used as a seat structure for other purposes where it is desired to make a shifting seat and one which can be bodily removed from its supports.

In the specification, I have used the term seat section meaning the seat proper, or cushion, and not the independent frame which usually supports the cushion.

By the above construction, it will be seen that I permanently connect the seat proper,

or cushion, to the movable back directly by arms, or links and, arms, so that the back can be shifted to either side of the seat.

When it is desired to remove the cushion, or seat proper, from the supporting frame, the back and seat are removed as a unit, leaving, in the present instance, the wall bracket and pedestal as the permament structure so that access can be had to all parts of the car floor.

I claim:

1. The combination of a seat cushion having a back pivoted thereto so that it can be shifted to either side thereof; with a permanent support upon which the seat cushion directly rests and from which it is removable with the back. 7

2. The combination in a car seat, of a fixed base having bearings; a seat cushion removably mounted ,inthe bearings; a back sec tion; and links permanently connecting the seat cushion to the back section so that the seat cushion and back can be removed from the bearing as a unitary structure.

3. In a car seat structure, the combination of a permanent seat support; a seat cushion mounted directly on the seat support; a back; permanent connections between the seat cushion and the back; and means engaging the fixed support so that, when the back is shifted from one side of the seat to the other, it will move the cushion in the opposite direction.

l. The combination in a car seat, of fixed bearings secured to the car body and each having a seat support; a seat cushion and back section permanently connected by links; a pivot shaft carried by the seat cushion and arranged to enter slots in the bearings, the seat resting on the seat supports so that the seat cushion and back section can be removed from the bearings vas a unit.

5. The combination in a car seat structure, of a pedestal and bracket, each havinga seat support; a seat cushion resting directly upon the seat support and arranged to bev detached v bodily therefrom; a back section; links connecting the back section with the seat cushion; and means engaging the bracket and pedestal sothat the seat cushion will be shifted when the back is turned from one side to the other.

6. The combination of a slotted seat support secured to a car body; a seat section and a back section; links connecting the two so that the back section can be moved to either side of the seat; a pivot shaft on the seat section extending into the slots on the seat support arms secured to the shaft and pins connected to the shaft also extending into the slots in the seat supports so that the seat cushion will be shifted when the back is turned and when it is desired to remove the structure the seat cushion, back and connectingarm, and links are removed as a unit. c

7. The combination in a car seat, of a back; a shaftmounted in bearings on the seat and extending beyond the endthereof; parallel links pivoted to the back and to the seat; a flat arm secured to each end of theshaft and pivoted to the back, said arms being of a greater width than the combined width of the links, whereby the links are retained on their pivots by the arms with out other fastenings. Y

8. The combination in a car seat, of a movable seat cushion; a back section; parallel links connecting the'back section to the seat cushion; a longitudinal. shaft mounted on the under side of the seat cushion; arms on the shaft pivotally connected to the back section; curved seat supports on which the seat cushion rests and having slotted extensions for the reception of the shaft; pins carried by the shaft, also extending into the said slots so thatwhen the back section is turned the seat cushion will slide on its supports and when the back section is in the central position the seat cushion, back and connecting members can be lifted off of the supports as a unit.
